Read Exif data from photo in disconnected Canvas app

[PowerAppUserCan]

I know how to read the Exif data from a photo uploaded to the server from a Canvas app.

But I have a requirement for an offline Canvas app to extract the Exif data from a photo.

Is there a way to extract the latitude and longitude from the Exif data of a photo (not from the phone GPS device) in disconnected mode?

Have you tried extracting the image into JSON format in powerapps? youd have to write a filter to find the data you want, but it should contain all the images metadata.

I can get the base64 string using JSON(UploadedImage1.Image, JSONFormat.IncludeBinaryData) but I do not know how to get the geolocation data and date out of the base64 string.

On the server I use this NuGet package https://www.nuget.org/packages/MetadataExtractor/ but I do not know how get the same metadata from base64 string.  Do you have any code that extracts the geolocation and date from the base64 string?

Hi @PowerAppUserCan :

I am afraid that the Canvas App cannot recognize the text in the picture when it is offline. If it is not offline, you can consider using AI builder to achieve this requirement.
